FLUME-GATE.

Specification of Letters Patent.

Patented Oct. 25, 1910.

Application filed June 17, 1909. Serial No. 502,709.

To all whom it may concern: Be it known that I, MATT H. WORLEY, acitizen of the United States, residing at Redlands, in the county of SanBernardino and State of California, have invented new and usefulImprovements in Flume-Gates, of which the following is a specification.

An object of my invention is to provide a flume gate that is simple andefiicient in operation, inexpensive in-construction, that will notbecome clogged with sand or foreign matter when the gate is opened, andone that will be constantly maintained in spring pressed engagement withthe seat when in a closed position.

A further object is to provide a gate whose holder is protected againstaccidental breakage or injury.

I accomplish these objects by means of the device described herein andillustrated in the accompanying drawings, in which Figure 1 is a frontelevation of the gate in .position on a flume, portions being brokenaway for clarity of illustration. Fig. 2 is a central longitudinalsection of the gate taken 011 line 2-2 of Fig. 1. Fig. 3 is a plan Viewof the gate attached to a flume. Fig. 4 is a centrallongitudinal-section of a modified form of gate and holder.

Referrlng more particularly to the draw ings, 5 designates one of theside walls of a concrete flume provided with a transverse cylindricalopening 6 therein adjacent the bottom thereof. My improved gate, whichis attached thereto, comprises a. substantially cylindrical metal tube7, a portion of its wall being flattened as at 8 to form alongitudinally extending angular trough 9, that will contract the sizeof the stream passing therethrough when the slide is slightly raised,and serve to keep the passage free from sediment. Tube 7 is preferablyprovided on one end thereof with a flange 11 which is soldered orotherwise secured to the flat body portion 12 of the slide holder,registering with an aperture 13 formed therein, similar in configurationto the cross section of the tube. The edge of the metal around thisaperture is preferably forced outwardly to form a water tight seat 1 1for the slide 10 with a minimum of bearing or contacting surface, thusreducing excessive friction, between the seat and the gate to a minimum.At either side of the aperture on the body ortion 12 of the holder isformed a vertical y extending bearing ridge formed therein, instead ofbeing cut away,

from the body portion, as it is adjacent the aperture 13, is bent acrossthe outer face of the body portion, and its vertical edge 16 is solderedor otherwise secured to the opposite side 17 of the body portion to forma centrally and vertically disposed guideway or bearing surface 18 forthe spring 19 to bear against on a movement of the slide.

Spring 19 is preferably formed of flat spring brass, or othernon-corrosive metal and is riveted or otherwise secured to the upper endof the slide, the lower end being free. The upper portion of this springterminates in a convenient hand hold 20 for moving the slide. It will benoted from-an inspection of the drawings that instead of forming thespring in a circular arched form, as is common in springs of thischaracter, I have bent it so that a lar e ortion of the spring willcontact with the guideway 18 and effectually hold the slide inwater-tight engagement with its circular seat 14, and revent the loweredge of the slide from being forced outwardly.

The lower edge of the slide is inclined from the horizontal to permitthe greatest flow possible through the trough 9 with a minimum upwardmovement of the slide, as indicated in dotted lines in Fi 1.

The metal portion 12 of the slide holder is preferably covered when theslide is affixed to the flume with a coating of cement or concrete 21,as clearly shown in the various views of the drawings, to prevent anyaccidental displacement or inJury to the holder.

It will be observed from the foregoing description that by reason of thespring 19 contacting with the guideway 18 of the holder, that the slidewill be at all times constantly maintained in water-tight engagementwith the seat 14 formed on the holder.

In Fig. at of the drawings I have illustrated a modified form of te. Inthis construction instead of forming a seat. on the body o-rtion of theholder, I have secured the tu e to the holder near one end thereof, theend of the tube rojecting beyond the outer face of the b0 y 12 andforming a seat for the slide 10 to bear against, this form beingconsidered the cheapest and simplest form of seat, the rest of theconstruction in this form being identical with that illustrated anddescribed in the preceding forms.

Having described my invention what I claim as new and desire to secureby Letters Patent is 1. A flume gate, comprising a tube, a slide holderfastened to the tube near the end thereof, a slide movably disposed insaid holder, and resilient means secured to the slide to maintain theslide in. water tight engagement with the end of the tube.

2. A. flame gate, comp-rising a tube, a slide holder secured to an endof the tube, a. vertically extending guideway formed on said holder, aslide movably disposed in said holder, and a resilient means secured tosaid slide and disposed in said guideway.

3. A flume gate, comprising a tube, a slide holder fastened to the tubenear the end thereof, a slide movably disposed in said holder, and aspring secured to the slide, said spring bearing against a portion ofsaid holder and adapted tomaintain the slide in water tight engagementwith the tube.

4. A fiiurne gate, comprising a tube, a

slide holder secured to an end of said tube,

a slide uideway formed integrally with said hold er and extending beyondthe outer face of said holder to form a bearing, a slide disposed in theguideway of said ho der, and resilient means connected to said slide,said means having a sliding contact with the guideway formed on saidholder.

5. A flu-me gate, comprising a tube, a slide holder secured to the endof the tube, said holder provided withan aperture therein, the edge ofsaid aperture being raised to form a slide seat, said apertureregistering with the end of the tube, a slide vertically movable in saidholder, and a spring secured to said slide and bearing against saidholder 6, A- fiume gate, comprising a tube, a slide holder fastened tothe tube near the end thereof, a slide movably disposed in said holder,and resilient meanssecured to the slide and acting against'said holderto maintain the slide in water tight engagement with the end of thetube,

In witness that I claim the foregoing I have hereunto subscribed my namethis 3d day of June, 1909'.
